World number one tennis player Jannik Sinner has withdrawn from the upcoming US Open in New York due to a right knee injury.
The Italian star, who has not played since winning the Wimbledon title last month, confirmed on Friday that he is not ready to compete in the final Grand Slam of the year, where main draw action begins on August 30.
In a message published on his X account, Sinner explained that despite hard work alongside his team and medical staff, they were forced to make the difficult decision to pull out. He said recent court training sessions in Monte Carlo revealed that his right knee still required more time to heal fully.
Medical examinations and past tournament results
Sinner had undergone several medical tests in early August to determine whether he could reach peak fitness for the tournament, but ultimately decided against travelling to the United States. He expressed sadness and disappointment over missing the event, stating that New York holds a special place in his heart and that he had been eager to play in front of its electrifying crowd once again.
The Italian won the US Open title in 2024 and reached the final again in 2025, where he lost to Carlos Alcaraz by three sets to one. The US Open is held annually at Flushing Meadows in New York as the fourth and final Grand Slam tournament on the tennis calendar.

Carlos Alcaraz comeback and player reactions
Sinner's withdrawal comes just one day after Alcaraz confirmed his own return to competitive tennis following a four-month absence. The Spaniard had been out of action since injuring his right wrist at the Barcelona tournament in April. Alcaraz, who hails from Murcia, announced his comeback on social media by posting that he was ready to compete, alongside an image featuring the US Open logo.
Former champion Andy Roddick commented on the tournament lineup, describing Alcaraz as the most exciting player in tennis and noting that fans never know what to expect from him. Roddick added that a US Open without both Sinner and Alcaraz would have been a nightmare for the sport.
